Kathy spent ³₅ of her salary on a food processor and ²₃ of the remainder on a gas stove. If she saved the remaining $74, how much was her salary?
Fraction of the salary spent on the food processor = ³₅

Fraction of the salary on the remainder
= 1 - ³₅
= ²₅

Fraction of the remainder on savings
= 1 - ²₃
= ¹₃

Food Processor	Remainder		Total
3x3	2x3		5x3
	Gas Stove	Savings
	2x2	1x2
9 u	4 u	2 u	15 u

The remainder and the total amount on the gas stove and the savings are the same. Make the remainder and the total amount on the gas stove and the savings the same.  LCM of 2 and 3 is 6.

Total salary = 15 u

Amount spent of the food processor = 9 u
Amount spent on the gas stove = 4 u
Amount of savings = 2 u

2 u = 74

1 u = 74 ÷ 2 = 37

Kathy's salary
= 15 u
= 15 x 37
= $555

Answer(s): $555
